Power Steering - hydraulic or electronic steering?
I didn't really see a thread for this specific topic, so I thought I'd be safe in starting one. My question is, does anyone have a preference between hydraulic or electric steering in the Camaro? I only ask because, as I read reviews of some GM cars, I'm finding an abundance of electrically-powered steering systems. They haven't been totally negative, but it seems testers prefer the hydraulic setups. What are your thoughts on this? Personally, all I've ever really driven is my Jeep, so I have no basis for comparison between the two.

Hydraulic is more natural in feel, but electric conserves more energy and increases fuel efficiency. I'd expect the Camaro to have whatever steering setup can be found in the Commodore/G8 (etc.).

I'd like to see EPS on V6 models, hydraulic assist on V8 models. Maybe it could even be an upgrade for the V6 in an RS package. It is a simple trade-off between steering feel and economy.

This is what my Cobalt has, as per Chevy.com:

by the engine. When you're stopped, or going slow, you have vast amounts of power steering assist, I can literally turn from 100% left, to 100% right with my pinky finger and a small amount of force. Out on the road, it becomes slightly harder to turn as the electric motor lets off a bit. This helps aid stability. This is NOT the most road-sensitive steering. but I feel like it's 'cleaner'. Does that make sense? It's sharper, and by no means do you not feel the road at all, it's just more distant. The fact that it can be tuned to different suspensions gives me hope that, because I have the bottom of the barrel car, it can be altered to be more sensitive to the road in cars like Camaro. Now, the fact that it frees horsepower is almost a moot point on a V8, because it's already so powerful, that any loss to te power steering pump is negligable IMO. On I4's it's a different story. |

Guess I'd have to take the EPS over hydro...just kind makes sense.

Does EPS go with Electronic Stability control? I know it monitors where the steering wheel is turned to help control oversteer/understeer, but don't know if it uses EPS to do that or some other type of sensor.

Mazda has EPS and my old sport truck (97 1/2 ton) had Hyd. The truck was dropped with low profile tires etc. I would say that the EPS is definitely cleaner and crisper when manipulating the wheel. But the Hyd gave much better feedback from the road. Which made me more comfortable at higher speeds. I like the EPS for lower speed carving. But I feel the road much better with the hydraulic.
Example. In a high G turn (slow or fast) it is harder for me to tell when the tires are going to break loose with EPS than it is with Hyd. But, the steering wheel feels more "locked in" or "slotted" with EPS. Note: Mazda is FWD so that my blow my logic out the window.

I'd really prefer hydraulic over electric assisted. If you don't get electric assisted right it could be a disaster in steering feel. The new BMW Z4 had that exact problem and really hurt sales IMO. Would also prefer non-drive-by-wire throttle. Ever drive a 350z? The pedal feel is completely fake it's like driving a video game car.
Basically I just hope that steering and throttle aren't overly assisted in the Camaro. Too bad it seems like most manufacturers are going this way though :( |

My wife has it on her 2.5 Jetta and I like the feel. She likes how tight it is at faster speeds and at low speed the effort is pretty minimal. If it's simpler than hydraulic, I'm down.

I'd just assume the Camaro be more of a traditional hydraulic PS car.

My Cobalt has EPS (Electric Power Steering). There's no power-steering pump accesory driven by the engine. So, primarily - it frees up some power. It's an electric motor as opposed to a belt-driven one. Only one 'system'.

I've never had a vehicle with electronic steering, doesn't that mess with your feel of the road?

I also have a Cobalt like Dragoneye and you don't loose any feel of the road. But the Camaro is a heavier car and will probably need the hydraulic power steering.

Actually EPS does lose a lot of road and steering feel over hydraulic systems. Its fine on cars like the Cobalt because no one buys those with steering and road feel a high priority anyway, but on the Camaro stuff like that can be a problem.
